So I think I need to slightly adjust my throttle and pitch curves but I don't know which ones takes priority? I would think I would lessen the steepness of the pitch curve between points 3 and 4 (to somethign like 50,65 or 50,70) but then I do need to increase my throttle curve at those two points or what?
with this little bird I'd suggest getting the head speed to full rpm, I changed mine to 0,55,100,100,100, then you are just altering pitch whilst flying and makes switching to 3d mode is smoother

If you want it less touchy vertically your curves below mid are too low and the high point is a bit high unless you want that upper stick pop.

If you want to keep negative pitch move the points up to 42 ish-45-50-65-80ish. If you want more upper stick pop add 5 or so at a time to the last two numbers. If you dont need or dont want negative pitch something like 50-50-50-65-80ish will be much less jumpy

100% throttle is a good idea. Get the RPM/inertia up there and keep it there... Then all you have to worry about is pitch settings and you just "get what you get" when it comes to head speed. Again, it really doesn't matter as long as pitch doesn't bog the head/motor too much at full positive and negative pitch. You can't damage this head by "overspeeding" it. The dark days of grip bearings failing and blades flinging themselves off the heli are long gone.

Also, make sure your pitch travel adjust is the same for + and -. It's an easy thing to miss when setting up the dx6i and can definitely cause the collective to be "jumpy". When setting pitch travel adjust, make sure you do it with the left stick (collective) all the way up and all the way down and adjust both numbers to the same value.

The bottom line is that there's no reason not to get a V2. Any shaking issues you may hear about are just as likely to occur with the V1.
Not something I'd normally do (for example, 500 vs 1000 vs 3000 has little meaning), but when someone has fewer than 10 posts and just registered this month, I think it's worth pointing out, especially when they are making completely inaccurate statements.

I've just opened up my dx6i and adjusted the throttle stick to virtually no resistance, I think that may help you with the jumpyness too?
You don't have the ratchet still on from plank flying do you?

But then again I believe an immature individual like you doesn't have a large enough brain to comprehend how to do this.

3. You are a child. Just cuz i am new to the forums doesn't mean i don't know what i am talking about.

But then again who are you gonna trust the tool trying to get a laugh out of you or the person who wants you to avoid having a problem that many people have experienced and to avoid having to go to the trouble of returning/exchanging the product.

I was expecting these forums would contain a lot of friendly professionals offering help like koko. I guess not.



l just put out my opinion and if you change to the fast flight blades you cannot do aerobatics which is the point of the heli. I know that the vibration occurs with the hi-performance blades and the point of using these blades is to do aerobatics and you cannot do these tricks what is the point of buying it?
Please don't pop in here with false information and expect to be well received. As others have stated, there is no fundamental issue with the V2 mCP X. What you witnessed sounded like something as simple as a set of blades that weren't correctly balanced. A quick call to Horizon would bring another set of blades to your door in a few days if that were the issue out of the box. Further, I would think an experienced user (your friend is "quite experienced"?) could troubleshoot such a simple issue.

Personal attacks (immature, child, tool) are not allowed on RCGroups. We try to keep this a professional, friendly environment. Please familiarize yourself with the forum rules. Your post has been reported.

Good idea. I'll set my throttle to 100 across the board and then only play with my pitch curve to see if I can get it more comfortable.

This really wouldnt be a factor even if his travel was neg 65 / pos 80 as The travel adjust is the end points of the curve. His issue is more the pitch curve itself and is why it drops and climbs quickly

On a similar note the best way I have found to figure out max possible travel per pos or neg pitch is to max out travel and then back down until it almost doesnt bog at all on a pitch pump in while holding it in your hand.

Nice! You'll see how easy it is when all you have to tinker with is the pitch curve. I still recommend getting used to hovering at 3/4 stick if you want to eventually fly this thing to its full potential.

Also, do you know how to use the other flight modes other than "normal", also called "stunt mode" or "idle-up"? You'll still want a throttle curve that has zero at the bottom for takeoff/landing. Set that throttle curve in "normal" so you can stop the blades when it's on the ground.

If you want it less jumpy I would leave it as you have it and adjust your pitch curve. Faster is more stable but less forgiving too...

I am surpised no one else is telling you that you have too much negative and too much positive pitch on your normal curve..specially if you are using 30% rates and trying to get a mellow flyer

I think the way I have it now it hovers around 3/4 stick so I should be OK. I'll just keep playing with it while making sure I'm hovering at 3/4 stick.

I've done some flying around in Idle Up (100 across the board on throttle curve) and I was fine with it.

Thanks. I'll experiment and see what works. But I did fly a few packs with my throttle curve at 100 across the board and I was OK with it.

The only thing I probably need to do is to ensure that I don't have too much negative pitch below mid stick so I don't accidentally put it into the ground at full speed when I try to chop throttle. But I'm pretty good with the throttle hold switch so I should be OK
